Do all PSU's have a cooling fan.Just downloaded a few Motherboard updates from Micro Star also it came with PC Alert4 which shows the temperatures etc.It shows the system fan and the Cpu fan but under PS fan [I take it it means power supply] It shows nothing. I can hear the PSU fan turning it is not exactly quiet.I take it this is normal and I don't need to worry about it.
Just an old Tiny computer.Sorry but looked up SIW and cannot find any mention of PSU.I am replacing it next month but just wondered why it showed Zero under the speeds of the fans. Absolutely nothing on this computer to slow it down about 90% of disc space is free. I did notice while in SIW it said memory Maximum Capacity 512 Mb 2 slots of 250Mb.I did get 2Mb from Crucial last year but did notice it never used up anymore than about 480mb. Getting away from that I have had a good look at the Power Supply a few times when inside cleaning and would think it would be almost impossible to get it out and replace it. It is just a chipset motherboard with graphics the same.MS 6390. The CPU is showing at least 90% when running any security programs and Iwas thinking it was the power supply on the way out.I am sitting here listening to the PSU fan running I was just wondering why it was showing Zero on PC alert program.
